Notes:  
1. Dynamic characteristics are specified at 5.0V unless otherwise specified.  
2. All logic inputs except Encoder and Decoder Data clocks  
3. For and encoder/Decoder combination, Insertion loss contributed by a single component is half this figure.  
4. Driven with a source impedance of <100.  
5. Recommended values – See Figures 4, 5, 6, and 7.  
6. Group Delay Distortion for the full codec is relative to the delay with and 820Hz, -20dB signal at the  
encoder input  
7. An Emitter Follower output stage.  
8. 4V = 80%V , 3.5V = 70%V , 1.5V = 30%V , 1V = 20%V
